Abstract
The invention discloses a kind of tubaeform ventilation bubbler of mine main fan multilamellar, including: top curve intersection steel disc (1), bottom decussation steel disc (2) and multilayer nest air duct (3)；Multilayer nest air duct (3) is arranged on and is intersected steel disc (1) by top curve and in framework that bottom decussation steel disc (2) forms, multilayer nest air duct (3) is made up of with the cylinder nesting that radian and diameter are different several。The present invention utilizes described ventilation bubbler that mine air outlet air quantity is tapped and spread, and reducing air outlet dynamic pressure, improving fan static pressure and the purpose of the kinetic energy of recovery air outlet, thus effectively reducing energy loss。
Description
Technical field
The present invention relates to a kind of tubaeform ventilation bubbler of mine main fan multilamellar, belong to Mine Ventilator technical field。
Background technology
In existing colliery, the power consumption of chief ventilators accounts for about the 20% of full ore deposit power consumption, and in large number of mine, fan unit operational efficiency is less than 70%, and even some does not also reach 50%。Due to general operational efficiency on the low side, have a strong impact on the economic benefit of main fan in mine, so improving the operational efficiency of chief ventilators device, saving power consumption is one problem demanding prompt solution of many mines。
At present, the air quantity of one blower fan of large-scale mine reaches 250-300m3/ s, diffuser exit wind speed reaches 15-20m/s, and only diffuser exit wind flow energy loss electricity just reaches 50-100kW。Due to the restriction of conventional diffuser form, this part kinetic energy rejection cannot reclaim, and causes that existing ventilator diffuser becomes the main cause of energy loss。
Summary of the invention
The present invention solves the problem that cannot reclaim kinetic energy and cause energy loss bigger that existing mine ventilator diffuser exists, and then provide a kind of tubaeform ventilation bubbler of mine main fan multilamellar。For this, the present invention proposes following technical scheme:
A kind of tubaeform ventilation bubbler of mine main fan multilamellar, including: top curve intersection steel disc, bottom decussation steel disc and multilayer nest air duct；Multilayer nest air duct is arranged in the framework being made up of top curve intersection steel disc and bottom decussation steel disc, and multilayer nest air duct is made up of with the cylinder nesting that radian and diameter are different several。
As seen from the above technical solution provided by the invention, utilize described ventilation bubbler that mine air outlet air quantity is tapped and spread, reducing air outlet dynamic pressure, improving fan static pressure and the purpose of the kinetic energy of recovery air outlet, thus effectively reducing energy loss。

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention。
This detailed description of the invention provides a kind of tubaeform ventilation bubbler of mine main fan multilamellar, as shown in Figures 1 to 6, including: top curve intersection steel disc 1, bottom decussation steel disc 2 and multilayer nest air duct 3；Multilayer nest air duct 3 is arranged in the framework being made up of top curve intersection steel disc 1 and bottom decussation steel disc 2, and multilayer nest air duct 3 is made up of with the cylinder nesting that radian and diameter are different several。
The tubaeform ventilation bubbler of mine main fan multilamellar that this detailed description of the invention provides includes the framework being made up of top curve intersection steel disc 1 and bottom decussation steel disc 2, then is arranged in described framework by multilayer nest air duct 3。Wherein, multilayer nest air duct 3 can be made up of with the cylinder nesting of radian several, the material of cylinder can adopt steel, and several cylinders are placed in the framework of bottom decussation steel disc, then the steel disc that intersects with top curve again is connected, open at the top of cylinder and bottom and carved orthogonal groove, and also the top of the outermost layer cylinder of multilayer nest air duct 3 can be provided with annular flat board。
After the tubaeform ventilation bubbler of mine main fan multilamellar that this detailed description of the invention provides installed by the chief ventilators auxiliary device of existing mine, available multiple described mine main fan multilamellar tubaeform ventilation bubbler carries out shunting diffusion to mine air outlet is distinguished and admirable, the distinguished and admirable flowing of mine air outlet is regulated by the entrance of the cylinder of the different-diameter arranged on multilayer nest air duct 3, thus regulating the operation that mine air outlet is distinguished and admirable, a part of kinetic energy of fan outlet is converted into fan static pressure energy, thus improving ventilation blower effective power, form a kind of brand-new mine ventilation system。
The operation principle of the mine main fan multilamellar tubaeform ventilation bubbler that this detailed description of the invention provides is: tubaeform for described mine main fan multilamellar ventilation bubbler is arranged on mine air outlet place, installation form is for be uprightly seated on mine air outlet by tubaeform for described mine main fan multilamellar ventilation bubbler, and the diameter of maximum horn cylindrical is adjusted according to mine well head size, multiple horn cylindricals are fixed on air outlet by the available top/bottom part framework of fixed form, and metal loudspeaker cylinder quantity adjusts according to the actual ventilation of shaft production and well head size。
In an alternate embodiment of the present invention, the top exit of several cylinders of multilayer nest air duct 3 is arranged on one and half mutual spheres and intersects vertically with described hemisphere face, make to export the distinguished and admirable Radial Flow along ball, distinguished and admirable hemispherical to external diffusion, improve shunting effect further。
Adopt the technical scheme that this detailed description of the invention provides, utilize described ventilation bubbler that mine air outlet air quantity is tapped and spread, reducing air outlet dynamic pressure, improving fan static pressure and the purpose of the kinetic energy of recovery air outlet, thus effectively reducing energy loss。
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the embodiment of the present invention discloses; the change that can readily occur in or replacement, all should be encompassed within protection scope of the present invention。Therefore, protection scope of the present invention should be as the criterion with scope of the claims。
